摘要： At least two image formation devices are provided. Each image formation device has a writing optical device that forms a latent image on a photosensitive member and a developing device that develops the latent image into a visual image. If the writing optical device in one of the two image formation devices is broken down, then the latent image is formed using the writing optical device in other of the two image formation devices. The latent image is developed to obtain the visual image using the developing device of the image formation device with the broken writing optical device.

摘要： In a printer system composed of a plurality of printer devices, the speed of the recording medium to be printed and of the intermediate carrier in every printer device following a printer device is adapted to the changing dimensions of the recording medium. For example, the changes in the recording medium that occur due to the fixing of toner images on the recording medium and that lead to a degradation of the print image are considered in following printer devices.

摘要： A matte laser printer produces a photographic like image on media by repeatedly fusing the toners deposited thereon. In a preferred embodiment, repeated fusing is accomplished by utilizing a duplexing path in the printer. In an alternate embodiment, a processing flow direction of the media is selectively reversed after fusing to enable multiple fusing operations. In either case, toner forming the image on the media is more fully fused, thereby reducing light scatter, such that a photographic like image is produced.

摘要： A system and method are provided for generating a color plane in an image. For example, a noise generation device is coupled to at least one component within a laser imaging assembly to cause a random deviation in the placement of the spots within respective color planes. This random deviation advantageously alleviates the problem of misregistration, white gapping, and moiré patterns, etc. In one embodiment, a system is provided that includes a laser imaging assembly having a laser generating a laser beam that is optically coupled to a photoconductor, typically an organic photoconductive (OPC) drum. The laser beam is optically coupled to a number of predetermined positions on the OPC drum to generate an image on the OPC drum. A noise generator is operatively coupled, for example, to a component in the laser imaging assembly. The noise generator causes a random motion in the component, for example, thereby generating a random deviation of each of the predetermined positions on the OPC drum to which the laser beam is optically coupled.

摘要： When a user changes a density adjusting value (developing contrast), and even when variations in the usage state of process characteristics (of the photosensitive body and the developing device) of the cartridge change, the amount of recording agent consumed can be suppressed to be low, and a sharp line image can be recorded. An image forming apparatus of this invention includes an edge detecting portion for detecting an edge of image data, an image data correcting portion for correcting image data inside the edge so as to decrease its density, a laser driving circuit for forming an electrostatic latent image on a photosensitive body, and a correction value determining table for acquiring an instruction value for giving an instruction to correct a density contrast, wherein a correction condition for image data changes in accordance with an instruction value.
